Before The Lab
Before using the apparatus in this experiment, you must complete training in the safe use of lasers detailed on the Laser Safety Training page. This includes readings, watching a video, taking a quiz, and filling out a form.
Pre-lab Discussion Questions
It is your responsibility to discuss this lab with a professor or GSI on the first day of your scheduled laboratory period. This signed sheet must be included as the first page of your report. Without it you will lose 1/3 of a letter grade. As you read the write-up and references for this lab, think about and be prepared to discuss at least the following questions before you come to lab:
1. How does a laser trap work?
2. What is a Power Spectrum Density (PSD) Graph and what can it be used for?
3. What is meant by sensitivity and stiffness of an optical trap?
4. What are the safety requirements for working with this laser?

Completed on the first day of lab? (circle) Yes / No
Mid-lab Questions
By day 2 of this lab, you should have successfully created a slide with a dilute solution of 1 micron beads, turned on the laser, trapped a bead, and moved it vertically and horizontally. Start the Optical Trapping program and take real time data while the bead is trapped. Using the "Alt + Print Screen" command, copy the Power Spectrum Density graph and show it to a GSI.
